Australian star Mitchell Marsh has been admitted to hospital after a positive COVID-19 test.
The Delhi Capitals, who he is playing for in the IPL, released a statement confirming they are aware of Marsh's situation, and monitoring events closely.
The franchise also confirmed other staff members of the team had tested positive, but weren't displaying symptoms.
"The Delhi Capitals medical team is closely monitoring Marsh's condition," the franchise said in a statement.
"A few more members from the Delhi Capitals bio-bubble, including support staff members, have returned positive tests as well. Though they are all asymptomatic, their condition is being monitored closely by the franchise.
"All remaining members of the bubble are currently in isolation in their respective rooms, and will be tested regularly."
The veteran Australian all-rounder, who is still a part of Australia's white ball teams - although missed the most recent series against Pakistan with a hip injury - had only returned to action in the IPL last week.
The franchise is coached by Ricky Ponting, and also features David Warner, who moved to the club from the Sunrisers Hyderabad after he was cut by his long-term club leading into the 2022 season.
Delhi are currently eighth on the IPL table as the season approaches the halfway point.
This is Marsh's first season with the Capitals, having previously represented the Sunristers Hyderabad, the Rising Pune Supergiants, the Pune Warriors India and the Deccan Chargers, who he debuted in the competition for back in 2010.
